The U.S. Embassy in Zimbabwe said the resignation of Mugabe "marks an historic moment" for the country and congratulated all Zimbabweans who raised their voices.
The statement said that "whatever short-term arrangements the government may establish, the path forward must lead to free, fair and inclusive elections." The United States also urges "unwavering respect for the rule of law."
British Prime Minister Theresa May said the resignation of Mugabe gives Zimbabwe "an opportunity to forge a new path free of the oppression that characterized his rule."
The British leader said the Zimbabwean people have shown they want "free and fair elections and the opportunity to rebuild the country's economy under a legitimate government." May said Britain — the former colonial power — is "Zimbabwe's oldest friend" and will "help the country achieve the brighter future it so deserves."
